9.2 Torque Transducer Origin Error, Cal Check Error.
9.2.1 Code 1-0 TORQUE TRANSDUCER / ZERO VOLTAGE ERROR
Zero Level does not match master level read from tool EEPROM during power on initialization.
This abnormal is caused from;
1. When the tool transducer is sensing excessive torque due to pressure on the tool body.
2. If the controller or the tool cable is located in an electrical or magnetic noise field.
3. When the torque transducer, tool cable or the controller malfunctions.
RECOVERY:
1. Check that the tool has no external force applied to it (Nothing touching the tool assembly).
2. Verify that the cable or controller is not located near any high voltage transient power
sources. Relocate as required and reinitialize.
3. Exchange tool cable, tool and/or controller with known working units. Reinitialize the
system after each exchange and make note of any change in the location of the abnormal.
4. Replace the defective component.
9.2.2 Code 1-1 TORQUE TRANSDUCER / CAL VOLTAGE ERROR
Calibration Voltage Error during power on initialization.
This abnormal is caused from;
1. When the tool transducer is sensing excessive torque due to pressure on the tool body.
2. If the controller or the tool cable is located in an electrical or magnetic noise field.
3. When the torque transducer, tool cable or the controller malfunctions.
RECOVERY:
1. Check that the tool has no external force applied to it (Nothing touching the tool assembly).
2. Verify that the cable or controller is not located near any high voltage transient power
sources. Relocate as required and reinitialize.
3. Exchange tool cable, tool and/or controller with known working units. Reinitialize the
system after each exchange and make note of any change in the location of the abnormal.
4. Replace the defective component.
9.2.3 Code 1-2 TORQUE TRANSDUCER / ZERO CHECK ERROR
Zero Level Voltage loaded to memory from tool EEPROM during initialization does not match the
actual zero level during a self check with the self check function DISABLED.
This abnormal is caused from;
1. When the tool transducer is sensing excessive torque due to pressure or vibration during
the fastening cycle start.
2. If the controller or the tool cable is located in an electrical or magnetic noise field.
3. When the torque transducer, tool cable or the controller malfunctions.
RECOVERY:
1. Check that the tool has no external force applied to it.
2. Verify the tool mounting bolts are tight and nothing is causing excessive vibration to the
tool.
3. Verify that the cable or controller is not located near any high voltage transient power
sources. Relocate as required and attempt the fastening start input again.
4. Exchange tool cable, tool and/or controller with known working units. Apply start signal
after exchange and make note of any change in the location of the abnormal.
5. Replace the defective component.
